Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method of creating signal message common files for a mobile switching center, and in particular, to an improved method of creating signal message common files for a mobile switching center which is capable of directly creating a signal message common file based on a signal message descriptive file for a mobile switching center.

2. Description of the Conventional Art

The TDX-10 MX mobile switching center (hereinafter called as TDX-10 MX MSC) is a high capacity switching unit having a distributed structure formed of a plurality of processors each performed a predetermined function. More than one execution module which is created by a block, which is a unit of a mobile switching center, is loaded and performed. In each block, a signal message, which is called as an Inter Processor Communication (IPC), is exchanged, thus performing its inherent function, and an interoperation of the blocks based on a transmission of a signal message determines the operation of the entire switching center.

The technique for exchanging the signal messages is expressed by a signal message descriptive file by the related block, and a signal message common file is created based on the signal message descriptive file of each block, and then is compiled. Thereafter, an execution module is loaded into a corresponding processor, and the signal message is exchanged between the related blocks, thus performing a predetermined function. Therefore, in order secure a normal operation, the signal message should have a signal message identifier and a signal message name for a mobile switching center.

Here, the signal message common file correctively means a signal message defining file and a signal message identifier creating file which are needed for compiling a block source based on the signal message descriptive file.

In order to effectively process the above-described procedure, it is needed to accurately check an interrelationship between the signal message descriptive file which is registered by a software block operator and a system common file which is managed by a manager, and it is important to effectively and correctively manage a complex interrelationship between the signal message descriptive files. In addition, in the software block of the mobile switching center, since a high level processor is programmed by a CHILL language and a low level processor is programmed by a C-language and an assembly language, the signal message common files should be created based on the characteristic of a corresponding language.

However, the conventional tools are implemented using a unix shell script and a CHILL (CCITT high level language), and much time is required due to its characteristic. In addition, the signal message descriptive file which is programmed by C-language or assembly language has many problems for creating a common file. Therefore, since the operator of the block which is programmed by C-language or assembly language announces a signal message common file in a source program, thus using the same, it is very difficult for the operator to effectively a complex interrelationship between the files. In addition, much time and cost are required for repeatedly and sequentially performing a predetermined process such as a checking process of a signal message descriptive file which is programmed by a CHILL language and a signal message common file. Furthermore, in the case that there is a predetermined change in a few signal message descriptive files without changing a plurality of signal message descriptive files, the entire processes are disadvantageously performed, thus increasing time consumption, and it is difficult for the manager for managing a source program compile.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide a method of creating signal message common files for a mobile switching center which overcomes the aforementioned problems encountered in the conventional art.

It is another object of the present invention to provide an improved method of creating signal message common files for a mobile switching center which is capable of directly extracting and optimizing a token from a signal message descriptive file registered by a user without using a shell script and a CHILL compiler, and creating a signal message common file and a common file with respect to only a signal message descriptive file which is changed.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates the construction of a software which is needed to create a signal message common file for a mobile switching center. As shown therein, when the current version of a mobile switching center software is Mversion, "bin and doc" denote a directory having environment setting files, and "md and work_-- md" denote a directory having a signal message descriptive file which is newly registered by a manager and a signal message descriptive file which is previously registered and managed by a manager. "include" denote a directory having a system common file which is managed by a manager, and "sig" denotes a directory having a signal message common file which is created for an operator of each block to perform a compiling operation.

FIG. 2 illustrates the construction of a signal message descriptive file for a mobile switching center. As shown therein, "#" is always positioned in a first column as a separator for separating different signal messages in a signal message descriptive file. "Version name" denotes a version name of a software which is currently processed. "Message name" is should be announced in the entire mobile switching center under the rules set in the mobile switching center for increasing an interpreting ability of the signal message name. "Message characteristic" denotes a functional characteristic of a signal message and is formed of three digits of a priority, a signal massage kind, and a signal message type. "Outline for a message" denotes a description concerning the function of a signal message in order to increase an understanding level. In addition, ".dr" denotes an item for indicating a transmission and receiving block of a signal message and is always positioned in a first column. A "message transmitting side" should be defined in a system as a block name or process name which system transmits a signal message, and the block name or process name may be described thereby.

"-->" denotes an identifier for identifying a block name or a process name for transmitting and receiving a signal message.

"Message receiving side" should be defined in a system as a block name or a process name for receiving message. In addition, the description of the block name or the process name is available thereby.

"User's definition for message" denotes an item for defining a related document type when the type of the signal message is announced as a user's definition type based on "Message characteristic".

FIG. 3 illustrates a flow chart of a process for creating a signal message common file for a mobile switching center. As shown therein, a directory shape information is extracted for creating a signal message common file based on a "bin" directory of FIG. 1 in Step S1, and a block name list (in Step S2) which is registered in from the "doc" directory, an execution module name list (in Step S3) which is used in the system, and a processor name list (in Step S4) are made. Next, a newly registered block list is extracted from the "md" directory in Step S5, and a signal message list which needs an update from the signal message descriptive file in the "md" directory and the "work_-- md" directory is extracted in Step S6. In addition, a system common file is extracted in order to check the registered signal message and the common file in Step S7. An error is checked whether it is found in Steps S1 through S7 in Step S8, and if there is an error as a result of Step S8, an error message having an error message code is sent to a manager and operator in Step S9, and then the routine is completed.

If there is not error as a result of Steps S1 through S7, the signal message descriptive file in the "work_-- md" directory is inputted based on the block name list (of Step S2). A signal message name is extracted in Step S11 based on "#", which is a signal message separator of FIG. 2, from the inputted signal message descriptive file, and a signal message transmitting and receiving block is extracted from the ".dr" field in Step S12. In addition, it is judged whether the inputted signal message descriptive file of Step S10 exists in the list of a newly registered block. If the signal message descriptive file exists in the list of the block, it is judged in Step S14 whether the message exists in the signal message list of Step S6 in order to judge whether the corresponding signal message corresponds to the signal message which needs an update. At this time, if the corresponding signal message exists in the list which needs an update, the execution mobile name list, which is to be updated based on the execution module name list of Step S3, is made in Step S15, and the processor name list is made in Step S16 based on the processor name list of Step S4. In addition, a flag for indicating that there is a signal message common file which needs an update is set in Step S17. A signal message is added in Step S18 to the transmitting and receiving block which is extracted in Step S12 from the ".dr" field, and this signal message is judged in Step S19 to be the final signal message of the signal message descriptive file of Step S10. If the message is not the final signal message, Steps S11 through S18 are repeatedly performed with respect to the next signal messages based on "#" which is the signal message separator of FIG. 2, and if the signal is the last signal message, the corresponding file is judged to be the last signal message descriptive file in Step S20.

If the corresponding signal message does not exist in the list of Step S6 which needs an update, or if the same does not exist in the list of Step S5 of a newly registered block, since a signal message common file creating operation is not needed due to the corresponding block, the signal message is added to the transmitting and receiving block in Step S18, and then this signal message is judged in Step S19 to be the final signal message of the signal message descriptive file of Step S10. If the signal is not the final signal message, Steps S11 through S18 are repeatedly performed with respect to the next signal messages based on "#" which is the signal message separator of FIG. 2, and if the signal is the final signal message, the corresponding file is judged to be the final signal message descriptive file in Step S20.

The minimum signal message common file list related with the update signal message of the block changed during the above-described steps is created.

Next, a flag is set in Step S21 in order to indicate that there is a signal message common file which needs an update for creating a signal message definition file among the signal message common files based on the signal message common file update list. If the flag is not set, since there is not the common files to be newly created, the routine is finished. If the flag is set, the execution module name is inputted in Step S22 from the first order based on the execution module name list of Step S15 which is to be updated, and since the names of the signal message definition files are made different which are to be created in accordance with the characteristic of the processor, the corresponding block is judged to be whether it relates to the block of the high level processor or the low level processor in Step S23. If the corresponding block corresponds to the block of the high level processor, the signal message spec file is made such that the program made by the CHILL language is used for a compile in Step S24, and if the corresponding block corresponds to the low level processor, the signal message head file in made in Step S25 such that the program made of C-language is used for a compile. If the above-described routines are completed, the corresponding execution module is judged to be the final module based on the execution module name list of Step S15 which is to be updated, and if the module is the final module, a signal message definition file creating step is performed. However, if the execution module which is not in the execution module list of Step S15 exists, the above-described steps S22 through S25 are repeatedly performed with respect to the next execution module.

Finally, in order to create the signal message identifier file among the signal message common files based on the signal message common file update list, the processor names from the first name thereof are sequentially inputted based on the processor name list of Step S16, and the signal message identifier spec file is created in Step S28. Here, the signal message common files which are used for a compiling are different in accordance with the characteristic of the language of the source program, the name of the signal message identifier file should be differently created. Namely, the signal message identifier file is classified into a signal message identifier spec file and a signal message identifier head file. In addition, the signal message identifier spec file is classified into a file related to one high level processor only, a file related to a high level processor which performs a communication with low level processor, and a file related to more than two high level processors. In addition, the signal message identifier head file is classified into a file related to a low level processor which is programmed by an assembly language and a file related to a low level processor which is programmed by C-language. Therefore, in order to create a signal message identifier file for matching with the characteristic of each language, it is judged whether a corresponding execution module name is an MP_-- PP in Step S29, and when the module name is an MP_-- PP, the signal message identifier head file is created in Step S30.

When the signal message identifier file creating is completed with respect to one processor name, it is judged whether the name is the final processor name based on the processor name list of Step S16 which is to be updated, and if the name is not the final name, the above-described steps S27 through S30 are repeated. If the name is the final name, the signal message identifier with respect to the added signal message is updated in Step S32, and the signal message identifier file creating operation is completed. If the execution module name is not MP_-- PP, the name is judged to be the final processor name based on the processor name list of Step S16 which is to be updated, and if the name is not the final name, the above-described steps S27 through S30 are repeated, and if the name is the final name, the signal message identifier is updated in Step S32, and the signal message identifier creating operation is completed.

As described above, when creating a signal message common file to be matched with the characteristic of a mobile switching center software block which is variously programmed by a language such a CHILL language, C-language, assembly language, etc., the token is directly extracted based on a signal message descriptive file of each block registered by a software block operator, and an optimized signal message common file such as a signal message definition file and a signal message identifier file which are used for compiling a block source is created. In addition, since the common file is created with respect to only the signal message descriptive file which is changed, it is possible to effectively cope with the continuous variations of a plurality of data and correctively manage a complex interrelationship between the signal message descriptive files, thus reducing a managing and creating time of a common data and more easily performing a compile, whereby a package fabrication time is significantly decreased.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as recited in the accompanying claims.
